• Description: N,N,N’,N’-Tetramethylazodicarboxamide (also named as Diamide, TMAD) is a reagent used for the oxidization of thiols in proteins. It is used as a reagent in the Mitsunobu reaction in place of diethyl azodicarboxylate. It can be used to titrate protein gluotathiolation to discriminate from other protein modifications.
• Uses: Reported to be of use as a thiol oxidizing agent. Diamide has been used to titrate protein glutathiolation to discriminate from other oxidative protein modifications. Treatment increased protein glutathiolation in a concentration-dependent manner and had comparably little effect on protein-protein disulfide formation.
